The invention discloses a wireless ad-hoc emergency communication network based on network cluster and message ferrying. The network comprises an emergency on-site command center (ECC), multiple emergency rescue special communication nodes (ECNs), a great quantity of ordinary communication nodes (OCNs) and a moderate number of ferrying nodes, wherein the ECC can be used as a command coordination node of the whole emergency communication network and a cluster node of the ECNs in the coverage area of the ECC; the ECNs can be used as cluster nodes of the OCNs in the coverage area of the ECNs; the cluster nodes and gateway nodes are interconnected to form wireless backbone networks (WBNs), the OCNs are connected with handy WBNs to which the OCN belong; and relay communication can be realized among the OCNs in different WBNs through the ferrying nodes. The communication network provided by the invention dynamically integrates the network cluster mechanism and the message ferrying mechanism, thus enhancing the reliability and timeliness of information delivery.
